In an irreversible process taking place at constant T and P and in which only pressure-volume work is being done, the change in Gibbs free energy (dG) and change in entropy (dS), satisfy the criteria
(a) (ΔS)V, E > 0, (ΔG)T, P < 0
(b) (ΔS)V, E = 0, (ΔG)T, P = 0
(c) (ΔS)V, E = 0, (ΔG)T, P > 0
(d) (ΔS)V, E < 0, (ΔG)T, P < 0

Correct answer:(a) (ΔS)V, E > 0, (ΔG)T, P < 0
Explanation:
For spontaneous reaction, dS > 0 and ΔG and ΔG should be negative i.e. < 0.
